Think of the LEAP as a Microsoft Kinect for your computer monitor. If this works as well as the video above purports, the small $70 accessory could be a big hit amongst those of us who've always harbored hopes for a Minority Report/Prometheus-style user interface...
The San Francisco team behind the USB peripheral + software based LEAP are aiming high with their 3D, touch-free motion sensing and motion control device:
The Leap technology is 200 times more accurate than anything else on the market -- at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter.
Will the $70 device be a good thing for us desk jockeys who don't move anything except our mousing fingers, or will it be too tiring to manipulate and interact with your computer using your arms for more than a few minutes? I personally can't wait to try it out. The LEAP will be compatible with both OS X and Windows machines, with Linux support in the works. If you're as curious as I am, they plan to release a limited amount of the devices by winter, with full availability soon afterward. Full details here.
